Reason #3) JSON = JavaScript Object Notation (and the web <3s it) I use this code basically all the time - but there's plenty of other instances where this type coersion (especially knowing 0, '', null, undefined are all fasly values). #1) - Everything is objects (and that's awesome)Įnter fullscreen mode Exit fullscreen mode I'm going to avoid dissing other languages in my reasoning, because I'm not quite as familiar and wouldn't want to misspeak about features.
I'm going to present some reasons (in no particular order) why JavaScript might be the best of both worlds for coding challenges (but especially as an alternative to Python). On the other hand, people often like Python since it's similar to writing pseudocode, it has a super beginner friendly community, and is fast to iterate upon. Java is notoriously verbose, which is often against the spirit of fast iteration during interviews. C++ has a bit more convolution with memory management and iterators, but trades that for speed. It's often said that C++/Java are great choices because they're super fast, have wide standard libraries, and strictly typed.
This article applies to actual interview services too, whether that's HackerRank, CodeSignal, HireVue, or any of the other numerous testing services.įor beginners, it's often parroted that Python, Java and C++ are the "big 3" to learn for LeetCode. If you're unfamiliar with LeetCode, it's a way to practice interview-type coding challenges in a short time frame. However then duplicate values are removed from the set.In reality, the best language is the one you're comfortable with.īut if you're debating learning a non-strictly typed language, or stuck between several choices, I want to present a couple of reasons why JS might be worth a try.Įveryone is on the LeetCode grind these days. There is the problem (bug) that ntains will not be true on finding an other List instance with same values. I would really appreciate any hint on what to do. I've been looking for a way to optimize this, but can't seem to think of the answer. I got TLE on testcase 311/312 on LeetCode, which is a really large array with big values. Notice that the solution set must not contain duplicate triplets. Given an integer array nums, return all the triplets, nums, nums] such that i != j, i != k, and j != k, and nums + nums + nums = 0.
